The Four Main Tennis Court Line Names

The four main tennis court line names are the baseline, service lines, center markings, and sidelines. Each of these lines plays a crucial role in the game. The baseline marks the end of the court, where both players start each point.

The service lines are where the server must stand when delivering the ball. Center markings divide the court into equal halves and help players understand their positioning.

The baseline in tennis is the back boundary line that runs parallel to the net. Its purpose is to mark the endpoints of each side of the court.

The baseline is an essential component of the tennis court, determining the dimensions and layout of the playing area.

It is positioned farthest from the net and is where players start and end each point. The baseline is also used to help determine whether a ball is in or out of play.

Its measurements are consistent across all tennis courts, with a total length of 78 feet (23.77 meters) for a singles match and 36 feet (10.97 meters) for a doubles match.

Understanding the definition and purpose of the baseline is fundamental for players to navigate and excel on the tennis court.

Service Lines

Service lines on a tennis court are of utmost importance in serving. They differentiate the single and double service areas. These lines determine where the server can stand while delivering the service.

The location and dimensions of service lines are strictly regulated in professional tennis matches.

The single service line lies one and a half meters from the centerline, marking the outer edge of the court for singles matches.

On the other hand, the double service line is placed six and a half meters from the centerline, defining the limits for doubles matches.

Both lines play a crucial role in ensuring fair play and maintaining the integrity of the game. Players must understand service lines’ significance and adhere to them while serving.

They uphold the rules and maintain a level playing field for both participants.

Center Markings

Center markings on tennis courts serve an important purpose in positioning the players and facilitating an efficient game. These markings include the net posts and net strap, ensuring the proper net height and center strap tension.

They provide a clear reference point for players to gauge their position on the court and maintain the integrity of the game.

From serving to volleying, these markings contribute to the overall gameplay, allowing players to position themselves and make accurate shots strategically.

Without proper center markings, the game would become chaotic, and the players would struggle to maintain fairness and accuracy in their shots.

So, next time you step onto a tennis court, pay attention to these center markings and appreciate the value they bring to the game.


Sidelines are the boundaries of the tennis court, distinguishing the in-play area from the out-of-bounds sections. These lines play a crucial role in in vs. out calls during matches.

Players need to know these court line names to determine whether the ball has landed within or outside the designated area. Familiarizing oneself with these boundary lines is essential for accurate gameplay and fair decision-making.
